SUMMARY: Staff has prepared the draft Water Production Summary Report for Water Distribution Systems (WDSs) within the Monterey Peninsula Water Management District (District) for Water Year (WY) 2015. WY 2015 covers the 12-month period from October 1, 2014 through September 30, 2015. Preliminary computations indicate that 11,011 acre-feet (AF) of water were produced by the 148 recognized WDSs in the District during WY 2015. In general, recognized WDSs refer to systems that either: (a) have received a WDS permit, or (b) have been confirmed as a pre-existing system prior to District rules that expanded WDS permitting requirements. The California American Water (Cal-Am) main system, which is the largest WDS in the District, accounted for 9,666 AF or approximately 91% of the total production reported by WDSs in WY 2015.

RECOMMENDATION: This report is for informational purposes only. The Board should review the draft summary report and provide staff with any comments or questions. Staff will complete and file the final report, incorporating any late revisions, if this item is approved with the Consent Calendar.

BACKGROUND: All owners and operators of WDSs within the District are required to annually submit water production information to the District. In 1980, District Ordinance No. 1 defined a WDS as works within the District used for the collection, storage, transmission, or distribution of water from the source of supply to the connection of a system providing water service to any connection including all water-gathering facilities and water-measuring devices. Therefore, all wells within the District are considered to be WDSs. However, until the adoption of Ordinance No. 96 in 2001, only multiple-parcel WDSs were required to obtain a permit from the District. Other refinements to the Rules and Regulations governing WDSs were added with the adoption of Ordinance No. 105 in 2002; Ordinance No. 106 in 2003; Ordinance No. 118 in 2005; and Ordinance No. 122 in 2006.

One new single-parcel WDS was established in WY 2015 (Garcia) and one was amended (Oh Well). One multiple-parcel WDS (Mal Paso) was established in WY 2015, and the CAW system was amended several times (CAW/DBO Amendment, CAW/Ryan Ranch CHOMP Amendment, CAW/Mal Paso Amendment, and the Ryan Ranch-Bishop Emergency Interconnection). All of the potable water produced by the Sand City Desalination Plant was provided to the Cal-Am main system, and that amount (245.42 AF) and is reported separately on this table. In WY 2015, no water was delivered for customer Service to the Cal-Am system from the Aquifer Storage and Recovery (ASR) project. It is also noted that the Cañada Woods Alluvial, Cañada Woods Upland and Monterra Ranch WDSs have been merged into the Cañada Woods Water Company WDS since WY 2005, although they are reported separately here to facilitate comparisons from one year to another.

Each WDS must report the amount of water produced and where required, the amount of water delivered, in addition to the number of existing and new connections served during the reporting period. The information for WY 2015 is summarized in Exhibit 6-A. The WDSs shown are grouped by source area. This information is also incorporated into the District-Wide Water Production Summary Report, presented as the following item of the Consent Calendar of this packet. For comparative purposes, the Annual WDS Production Summary Report for WY 2014 is provided as Exhibit 6-B.

Production figures for three WDSs -- Bishop, Ryan Ranch, and Hidden Hills Units -- are reported separately from the Cal-Am main system, although Cal-Am owns and operates each of these satellite units. The Ryan Ranch Unit was acquired and annexed into the Cal-Am system in November 1989. The Hidden Hills Unit, which formerly reported as the Carmel Valley Mutual Water Company, was acquired and annexed into the Cal-Am system in March 1993. The Bishop Unit, which has been operated by Cal-Am since September 1996, was acquired and annexed into the Cal-Am system in July 1999. Although water production and delivery values for the Bishop, Hidden Hills and Ryan Ranch Units are reported separately from the values for Cal-Am’s main system in this report, they are included in Cal-Am’s total production in the District-wide Production Summary Report (Exhibit 7-A) as “Cal-Am Wells Within the Water Resources System”.

Three systems that are operated by the Cañada Woods Water Company (CWWC) are tracked separately in this report but are part of an interconnected system. The production shown in Exhibit 6-A for Monterra Ranch includes water produced from wells that was sent to the system’s reverse osmosis (RO) desalination plant and un-treated water that was produced for non-potable purposes. The consumption loss for the CWWC includes water line flushing and unmetered construction and irrigation uses. Beginning in WY 2010, the system loss calculation was revised by CWWC to present a single composite system loss value.

District-wide - Total WDS production within the District for WY 2015 was 11,011 AF. Of this total, the Cal-Am main system (i.e., not including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for 91% of the water produced by WDSs within the District. The other 147 systems (i.e., including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for the remaining 9 percent of production. Total WDS production for WY 2015 is 868 AF (7%) less than the production reported for WY 2014. During WY 2015, Cal-Am’s main system production decreased by 958 AF (9%), while reported non Cal-Am WDS production decreased by 90 AF (7%), relative to production in WY 2014.

Monterey Peninsula Water Resources System (MPWRS) - Total WDS production from the MPWRS, which includes the Carmel River and its tributaries, the Carmel Valley alluvial aquifer, the Seaside Groundwater Basin was 10,355 AF in WY 2015.

The comparisons below include production from Cal-Am’s satellite systems (Bishop, Hidden Hills and Ryan Ranch Units) that derive their source of supply from the Laguna Seca Subarea (LSS) of the Seaside Groundwater Basin. The LSS was added to the MPWRS with the adoption of Ordinance No. 135 on September 22, 2008. Total WDS production within the MPWRS decreased by 1,055 AF (9%) in WY 2015 compared to production in WY 2014. In WY 2015, production by Cal-Am from within the MPWRS decreased by 991 AF (9%) and the combined production from 22 other active systems within the MPWRS decreased by 64 AF (15%), relative to production reported for WY 2014.
